Shut-down Procedure
1 . Remove the used nozzle by pushing down on the
nozzle ejector .
2 . apply petroleum jelly to the face of the InSTa-FlO™ Gun .
3 . Reinsert the used nozzle . This provides an airtight
seal during storage .
4 . Turn off the in-line on-off valves . The valve handles
should be perpendicular to the chemical lines .
5 . Turn off the on-off valves located near the chemical filters .
The valve handles should be perpendicular to the
chemical lines .
6 . Turn off the chemical tank valves of the “a” and “B” tanks . The
handles should be perpendicular to the valves .
7 . Turn off the yellow-coded nitrogen intake valves of the “a” and
“B” tanks . The handles should be perpendicular to the valves .
8 . Turn off the nitrogen cylinder by turning the valve on the top
of the nitrogen cylinder in a clockwise direction .
9 . Back out both nitrogen regulator valve stems until they are
freewheeling .
10 . Coil the chemical lines to prevent possible tripping
and damage .
Section 7
Storage
1 . Store in a dry area .
2 . Store between 60°–80°F (16°–27°C) .
3 . Short term storage between 45°–60°F (7°–16°C) is permitted .
4 . dO nOT store at temperatures above 120°F (49°C) .
5 . dO nOT not store near steam or hot water pipes .
6 . dO nOT store near chimneys or heat vents .
7 . If a partially used system remains inactive for a period of time,
the system should be pressurized and purged every two weeks .
This will prevent crystallization of the chemical in the hoses .
8 . unopened chemical tanks have a shelf life of approximately
one year .
Section 8
dO nOT breathe vapor or spray . Proper Personal Protective Equipment
and ventilation are required . See product SDS and Section 2 of this
manual for further information . Follow all precautions for product .
Re-Start-Up
1 . Open the nitrogen valve fully to pressurize the system .
2 . Open the two sets of valves on the chemical tanks for the a and
B sides and then the valves on the gun .
3 . Remove the cured nozzle that you left attached to the gun .
4 . Spray into a waste container . Ensure that you have good flow
from both the a and B side hoses .
5 . Clean the face of the gun . attach a new nozzle .
6 . Spray a test sample to ensure good quality foam .
7 . Resume spraying .
Re-start Procedure
8 .1 System Pressurization
1 . Verify that the valve stems on the regulator are backed
out and are freewheeling .
2 . Open the nitrogen bottle valve by turning the knob on top of
the cylinder counter-clockwise . If a hissing sound occurs,
further tighten the nitrogen regulator valve stem with an
adjustable wrench . use only in well ventilated areas . Wear
suitable respiratory protection .
